This becomes very useful in terms of autocompletion.Įach word is treated with two spaces prefixed and one space suffixed to balance the number of trigrams for a n-character word. The more number of sequence matches means the high similarity between the words. The comparison aims to find the number of shared sets between the two words. For finding the similarity between two words, wordA and wordB, wordA is split into three letter sequences and compared with the three letter sequence combinations computed from wordB. In a trigram the variable sequence in n-gram is 3. Well, what does that mean, exactly? It means finding matching words by maintaining variable sequences of characters in a word. In the fields of computational linguistics and probability, an n-gram is a contiguous sequence of n items from a given sequence of text or speech. Note: Remember to do the changes with owner and permissions.A trigram is nothing but an n-gram with three letter sequence.

Now, let's download Redmine and configure itįirst some database stuff.
Postgres=# CREATE DATABASE redmine WITH ENCODING='UTF8' OWNER=redmine TEMPLATE template0
PG POSTGRES APP RAILS PASSWORD
Postgres=# CREATE ROLE redmine LOGIN ENCRYPTED PASSWORD '' NOINHERIT VALID UNTIL 'infinity'
PG POSTGRES APP RAILS INSTALL
It should be noted that Redmine and all it's dependencies are available as packages in Debians' repo's, so there is no need to download Redmine from svn as we will do in this howto.įirst we become root and install some needed packages:Īpt-get install postgresql-8.4 apache2 subversion rake rubygems libopenssl-ruby libpgsql-ruby libapache2-mod-passengerīefore configuring redmine we need to create a user and a database in Postresql. This howto is similar to the HowTo Install Redmine on Debian with Ruby-on-Rails and Apache2-Passenger, but a little shorter and uses Postgresql instead of Mysql as the database server.
